[OSM-talk] OSM tagging validation lib

[john whelan]

But what I suspect could be done is when iD in invoked from a HOT project
it could restrict the options on things like highways to those in the wiki
https://wiki.openstreetmap.org/wiki/Highway_Tag_Africa
which would save a lot of living_streets etc. being added in parts of
Africa where there aren't any.  Also reduce the numbers of highway=footway
rather than path.

We might even get a few more building=yes tags rather than the range we get
at the moment.

Thanks John
